Why does the MATLAB* Help Window not open, show a blank window, or give a “No Internet Connection” error when I click on the Help icon inside DSP builder

Description

The MATLAB* Help Window might not display the documentation content properly even when the computer has internet access. The user might experience the same issue when clicking on the MATLAB Help icon within the DSP Builder tool.

Possible failure modes include:

• The Help link does not open a window at all.
• The Help content does not load and only shows a blank page.
• The "No Internet Connection" message is shown.

Resolution
